Summary: Livestock, particularly cattle, contribute significantly to agricultural greenhouse gas emissions in South Africa. This study aimed to investigate causal factors of these emissions and calculate methane emission factors for each province, as well as factors required for nitrous oxide emissions. The study also provided emissions data for different cattle types, highlighting commercial beef as the main contributor to total emissions.

Summary: The objective of this study was to investigate the viability of using retorted oil shale as urea coating to reduce N losses by ammonia volatilization. The results showed that using retorted oil shale-coated urea significantly decreased the ammonia volatilization-induced N losses without increasing greenhouse gas emissions.

Summary: This study investigated the impacts of different alkaline biochars (from walnut shell, coconut shell, and coal) on gas emissions from liquid pig manure. The results showed that the application of biochars significantly increased NH3 and CH4 emissions, with the absorbed N content of the biochars lower than the enhanced gaseous losses through NH3 emissions. The total greenhouse gas emissions were also higher with biochar application, mainly due to enhanced CH4 emissions.

Summary: We measured greenhouse gas emissions and evaluated manure management in beef cattle feeding in northeast Thailand. The addition of rice straw was found to decrease methane emission and reduce the relative abundance of methane-producing bacteria. Additionally, it showed potential for reducing nitrogen oxide emissions.

Summary: Studies have shown that manure covered by organic materials can effectively reduce greenhouse gas emissions. However, there is limited research on the bacterial communities in manure and the mechanisms responsible for reducing gas emissions. This study investigated the effects of cornstalk and sawdust coverings on greenhouse gas emissions during sheep manure storage. The results showed that organic material coverings reduced nitrous oxide emissions through physical adsorption and bacterial transformation, while increasing methane emissions by creating anaerobic zones. Overall, the coverings reduced carbon dioxide equivalent emissions and had minimal impact on bacterial diversity and community.

Summary: The potential for reducing non-CO2 greenhouse gases is highly uncertain, and this uncertainty has significant implications for achieving the goals of the Paris Climate Agreement. A systematic estimate of the uncertainty in non-CO2 greenhouse gas mitigation reveals that reaching the global climate targets is challenging due to technical limitations and uncertainties in mitigation options.

Summary: Modified biochars, such as sodium ferrate-modified biochar (Fe@C), have been found to effectively reduce methane and nitrous oxide emissions in paddy fields, leading to increased rice yields and organic carbon content in soil. The use of sodium ferrate alone also significantly reduced N2O emissions. The results suggest that Fe@C could be a promising management measure for enhancing soil carbon content and reducing greenhouse gas emissions.

Summary: Rice paddies are an important source of staple food for half the global population, but they also contribute significantly to greenhouse gas emissions. This review explores the characteristics of these emissions and the potential strategies to mitigate their effects. The study finds that management practices play a crucial role in determining the level of emissions, and that future climate change is likely to increase these emissions. However, integrated agronomic management strategies offer potential for reducing greenhouse gas emissions.

Summary: The combined application of green manure and inorganic fertilizer can increase CO2, CH4, and N2O emissions, as well as grain yield. The effects of this practice on greenhouse gas emissions and yield are influenced by initial soil conditions, green manure application methods, and timing. Green manure substitutes for inorganic fertilizer can increase GWP and yield in areas with high initial soil pH and low C:N ratios.

Summary: Coastal wetland restoration is a significant activity for achieving greenhouse gas reduction targets, improving water quality, and reaching sustainable development goals. This study in subtropical Queensland, Australia, measured carbon abatement and nitrogen removal potential in restored coastal wetlands. The results showed that tree growth, soil accumulation, and reduced fertilization led to positive carbon abatement, even considering increased methane emissions and enhanced denitrification levels.

Summary: Hydrothermal carbonization is a green and sustainable technology for treating manure-based wet waste and recovering nutrients. Applying manure-derived hydrochar to agricultural soils can disrupt soil stoichiometry and affect greenhouse gas emissions. However, the relationship between soil stoichiometry and methane and nitrous oxide efflux under manure and manure-derived hydrochar application needs further clarification.

Summary: This study compared the effects of broadcast and low disturbance manure incorporation on alfalfa yield, ammonia, and nitrous oxide fluxes, highlighting the relationship between manure application and precipitation events on N2O fluxes. The results emphasize the importance of quantitatively evaluating agri-environmental tradeoffs to determine the optimal manure application method.

Summary: Current agricultural practices for manure storage contribute significantly to greenhouse gas emissions, particularly methane. This study compared the effects of acidification with sulfuric acid and thermal treatment on suppressing methane emissions and preserving methane potential. The results showed that thermal treatment significantly enhanced methane potential, while acidification reduced methane yield compared to non-treated manure. The study suggests that thermal treatment, such as pasteurization, is a promising alternative to the widely used acidification method.

Summary: High-rate algae ponds can effectively combine wastewater treatment with biomass production for biofuel. However, the presence of algae in HRAPs can negatively impact pathogen removal. Factors such as high pH, dissolved oxygen levels, and mixing can enhance sunlight-mediated pathogen removal. Predation may also play a role, but further research is needed to understand its quantitative impact.

Summary: This study aimed to verify the occurrence and significance of dark decay, alkaline-pH toxicity, and sunlight direct damage in High Rate Algal Ponds (HRAPS) during wastewater treatment. Data from monitoring Escherichia coli cell count in pilot HRAPs were used to create a model for E. coli removal prediction. The model predicted that dark decay had the highest yearlong mean contribution to E. coli removal in HRAPs, followed by sunlight mediated disinfection and pH toxicity.
